Conceptual Design of Electrical Power Subsystem for Cube Satellite with Permanent Magnet Attitude Stabilization Method

큐브위성용 상용 전력계 부품을 적용한 영구자석 자세제어 안정화 방식 큐브위성의 전력계 개념설계

The role of Electrical Power Subsystem (EPS) is to generate a power and distribute it to the electrical devices for the system operation. For on-orbit operation of cube satellite, it is also necessary to supply power to on-board mission devices as commercial satellite does. Recently, commercial EPS products dedicated for the cube satellite application has been developed and widely used for the power subsystem design. In this paper, a permanent magnet attitude stabilization method without external power has been introduced because it has advantage from power consumption point of view and the EPS design of cube satellite by applying the commercial EPS products has been introduced and investigated. This paper also deals with the specification of the commercial EPS products for the beginner of the cube satellite design.
